[the perspective offered by archaeology], "that of material culture […] is in direct conflict with the findings of the other discipline claiming a key to the solution of the ‘Aryan Problem’, linguistics" ...Archaeologists and anthropologists... [like] Jim G. Shaffer and Diane A. Lichtenstein, who “stress the indigenous development of South Asian civilization from the Neolithic onwards, and downplay the role of language in the formation of (pre-modern) ethnic identities”; J. Mark Kenoyer, who “stresses that the cultural history of South Asia in the 2nd millinnium B.C. may be explained without reference to external agents”, and Kenneth A.R. Kennedy, who concludes “that while discontinuities in physical types have certainly been found in South Asia, they are dated to the 5th/4th, and to the 1st millennium BC, respectively, too early and too late to have any connection with ‘Aryans’.”

The idea has recently been challenged by archaeologists, who ― along with linguists ― are best qualified to evaluate its validity. Lack of convincing material (or osteological) traces left behind by the incoming Indo-Aryan speakers, the possibility of explaining cultural change without reference to external factors and ― above all ― an altered world-view (Shaffer 1984) have all contributed to a questioning of assumptions long taken for granted and buttressed by the accumulated weight of two centuries of scholarship....

Erdosy (1995a), who is prepared to find "some support" for small-scale migrations associated with the intrusive BMAC elements noted earlier, nonetheless states: "Several cultural traits with good Vedic and Avestan parallels have been found widely distributed between the southern Urals, Central Asia and the Indo-Iranian borderlands. However, even allowing for the uncertain chronology of Central Asian sites, few of these traits show the northwest-southeast gradient in chronology predicted by our linguistic models." Rather, in the manner of other traits commonly associated with the "Aryans" within South Asia, "they originate in different places at different times and circulate widely, undoubtedly through the extensive interaction networks built up in the mid-3rd to early 2nd millennia B.C." The main point is that "it is impossible, thus, to regard the widespread distribution of certain beliefs and rituals, which came to be adopted by Indo-Iranian speakers, as evidence of population movements" (12).

As for Burrow‘s thesis that some place names reflect the names of geographical features to the west, and thus preserve an ancestral home, they once again rather rely on an assumption of Arya migrations than prove it. [...] His cited equivalence of Sanskrit Saraswati and Avestan Haraxvaiti is a case in point. Burrow accepts that it is the latter term that is borrowed, undergoing the usual change of s- > h in the process, but suggests that Saraswati was a proto-Indoaryan term, originally applied to the present Haraxvaiti when the proto-Indoaryans still lived in northeastern Iran, then it was brought into India at the time of the migrations, while its original bearer had its name modified by the speakers of Avestan who assumed control of the areas vacated by proto-Indoaryans. It would be just as plausible to assume that Saraswati was a Sanskrit term indigenous to India and was later imported by the speakers of Avestan into Iran. The fact that the Zend Avesta is aware of areas outside the Iranian plateau while the Rigveda is ignorant of anything west of the Indus basin would certainly support such an assertion.

Evidence for the characterization of Dasas and Dasyus as black is tenuous in the extreme.... Even apparently clear indications of historical struggles between dark aborigines and Arya conquerors turn out to be misleading.... [The Dasas and Dasyus] appear to be demonic rather than human enemies.... It is a cosmic struggle which is described in detailed accounts that are consistent with one another.”
